I have a requirement to download files from the public URL of any OneDrive file or folder belonging to another user using the Django framework. I have written the code, but it gives me an error when accessing the file_id.

I am trying to access the file info from below code, but it is now working I have also give the and use msal library for the same

1. #permission

   1. “Sites.Read.All”,

   2. “Sites.ReadWrite.All”,

   3. “Files.ReadWrite.All”,

   4. “Files.Read.All”

#code where the problem occurs

file_info = get_drive_item_id(access_token, encoded_share_url)

#code
